Has this ever happened to you? Things are going great in a relationship. And then, you find out that your significant other loves music that you hate. Or doesn't understand your taste in music at all. Or is really critical of the music that you enjoy. And suddenly, dating that person just doesn't seem like such a good idea anymore.

We talk with Salie and neuroscientist, musician and author Daniel Levitin about what we can actually learn about people's personalities from their musical taste -- and why music can send up such glaring warning signs in a relationship.
